No one really knows for sure, and the question of why are there different bios for each board goes unanswered. When we speculate, the handful of people 'in the know' i think just laugh at us

One thing is for sure, just as many people are getting great overclocks on the UD5 as the Extreme. So unless you want to watercool the X58, your cpu will be your limiting factor not the board.
